Description

【0001】
【発明の属する技術分野】
本発明は、橋梁、建造物等からの落下物を捕獲する落下物捕獲装置に関する。
【0002】
【従来の技術】
従来、橋梁、建物等のうち常時人が多く集まるような場所には、落下防止用の落下防止ネット、保護柵又はトンネルネットなどが取り付けられ、人又は物体の落下を未然に防ぐ構造が取られていた(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開平10−15095号公報
【0004】
【発明が解決しようとする課題】
しかしながら、従来の落下防止ネット、保護柵又はトンネルネットなどは、著しく景観を損なうものであり、他の構造物又は景色など対して違和感を与えるなどの欠点を有していた。また、従来の落下防止ネット、保護柵又はトンネルネットなどは、風を受けることで構造物に悪影響を与え、火災時においては救助者の救助活動の妨げになるなど避難、救助に支障をきたす構造物となる恐れも否定できないものであった。
【0005】
また、一時的に人が集まる場所又は集まる人が少ない場所などでは、転落、落下について注意を喚起する立て看板などが設置され、他の防護措置が取られていない場合がある。しかし、このような場所では、事故が起こったことも判らず、例えば人が転落した場合、転落直後に死亡に至らなくても放置されることで人命を落とすことが考えられる。
【0006】
本発明は、上述した事情に鑑みてなされたもので、風を受けることなどによる構造物への影響を抑制でき、火災時における避難及び救助へ支障を及ぼすことを回避でき、景観を損なう又は違和感を持つなどの不都合を抑制し、落下危険ゾーンに人又は物体が侵入したときにだけ捕獲機能を発揮することができる落下物捕獲装置を提供するものである。
【0007】
【課題を解決するための手段】
上記課題を解決するために、請求項1記載の落下物捕獲装置は、物体が所定領域に入ったことを検出するセンサと、前記センサの検出信号に応じて圧搾空気を送出する圧搾空気送出手段と、前記圧搾空気送出手段から送出された圧搾空気によってシート形状となる捕獲用シートとを有することを特徴とする。
【0008】
ここで、所定領域とは、例えば落下危険ゾーンである。そしてセンサは、複数種類及び複数個の検出手段からなることが好ましく、人又は比較的大きな物体が落下危険ゾーンに侵入したことを検出できるものであることが好ましい。また、圧搾空気送出手段は、前記センサの検出信号で動作するとともに、高速に動作する電磁弁などの開閉器を有し、この開閉器を介して圧搾空気を送出するものであることが好ましい。
【0009】
また、捕獲用シートは、橋梁、建物などの下部又は側部に折り畳みなどされて格納されていることが好ましく、例えば折り畳まれたゴムボートに空気を挿入することでボート形状となるように、前記圧搾空気によってシート形状となることが好ましい。そこで、落下危険ゾーンに人などの物体が侵入すると、収納などされていた捕獲用シートが圧搾空気によってシート形状に拡張するなどして、落下危険ゾーンから落下した人などの物体を捕獲用シートが捕獲することができる。
これらにより、本発明によれば、落下する人の人命保護及び物体落下による破壊を防止することができ、落下地点において落下物に巻き込まれることによる事故発生及び物体の破壊等の防止をすることができる。
【0010】
【発明の実施の形態】
以下、図面を用いて本発明の実施形態を説明する。
[第1実施形態]
図1は本発明の第1実施形態に係る落下物捕獲装置の概略構成を示すものであり、図1(a)は正面図であり、図1(b)は側面図である。図1では、橋梁に落下物捕獲装置を設置した実施形態を挙げている。本落下物捕獲装置は、支柱1、圧力センサ2−1、遮断検知センサ2−2、捕獲用シート支持用ワイヤ3、高速開閉器4、配管5、圧搾空気タンク6、制御システム7、捕獲用シート8、格納容器9及び捕獲用シート固定器具10で構成されている。
【0011】
支柱1は、捕獲用シート支持用ワイヤ3の起点となるものであって橋梁に固定されている。圧力センサ2−1は、欄干等に取り付けられるセンサであって重量を検出する。遮断検知センサ2−2は、支柱1に取り付けられており、物体が赤外線又はレーザ光などを遮断したことを検知して人又は物体が所定領域に侵入したことを検出する。
【0012】
捕獲用シート支持用ワイヤ3は、捕獲用シート8を支持するワイヤである。高速開閉器4は、配管5から捕獲用シート8ヘ圧搾空気を送出するか否かを高速に切り替える開閉手段となる電磁弁などからなるものである。配管5は、圧搾空気タンク6から捕獲用シート8へ送出される圧搾空気の通路となるものである。圧搾空気タンク6には、圧搾空気が充填されている。制御システム7は、圧力センサ2−1及び遮断検知センサ2−2の検出信号に基づいて高速開閉器4の動作を制御するものである。捕獲用シート8は、配管5などを介して送出された圧搾空気によって拡張してシート形状になるものである。格納容器9は、捕獲用シートがジャバラ状に折り畳まれて収納される容器である。捕獲用シート固定器具10は、圧搾空気によってシート形状に拡張された捕獲用シート8の一辺などを固定又は支持するものである。また図1における符号Aは、捕獲用シートの拡張方向を示す。
【0013】
人又は物体が落下危険ゾーンに侵入すると、圧力センサ2−1及び遮断検知センサ2−2からなる複数種類及び複数個のセンサから検出信号が出力される。ここで、落下危険ゾーンとは、絶対に落下(転落)する位置をいう。例えば、橋梁の欄干上に設置された重量を感知する圧力センサ2−1と、橋梁と一体的に構築されているシート支持用ワイヤ3の起点となる橋梁に固定された支柱1の欄干の外側の絶対に落下(転落)する位置に配置されている遮断検知センサ2−2との双方が動作することで、上記侵入を感知し検出信号を出力する。
【0014】
これらの圧力センサ2−1及び遮断センサ2−2から出力された検出信号は、制御システム7に送られる。制御システム7は、検出信号を受信して圧力センサ2−1及び遮断センサ2−2双方が同時に動作したこと認識することで、落下危険ゾーンに人又は物体が侵入したと判断する。すると、制御システム7は、危険落下ゾーンに人又は物体が侵入したとの判断により、瞬時に高速開閉器4に開放信号を送出してその高速開閉器4を「開」状態にする。これにより、瞬時に圧搾空気タンク6に充填されていた圧搾空気が配管5及び高速開閉器4を通って捕獲用シート8に送り込まれる。すると、捕獲用シート格納容器9にジャバラ状に折り畳まれて収納されている捕獲用シート8がシート形状に広がるように拡張する。この拡張した捕獲用シート8は、落下物を捕獲する捕獲機能を発揮する。
【0015】
図2は捕獲用シート8が動作したときの状態を示し、図2(a)は正面図であり、図2(b)は側面図である。図3は捕獲用シート8が格納容器9内にジャバラ状に格納されている状態を示し、図3(a)は拡張方向から見た正面図であり、図3(b)は上面図であり、図3(c)は側面図である。図4は捕獲用シート8が捕獲機能を有効にしたときの状態を示し、図4(a)は上面図であり、図4(b)は側面図である。
【0016】
捕獲用シート8は、図1から図4に示すように、ゴムボートが折り畳まれた状態から本来目的のボート形状になるのと同様に、空気を送り込むことでシート形状となるものである。そして、捕獲用シート8は、圧搾空気が注入されると、木材程度の強度を持つゴム引き素材などで構成されており、板が張り出したような状態になる。ただし、捕獲用シート8だけでは落下物体を支えきれない。そこで、捕獲用シート8が空気注入されることで拡張することにより、捕獲用シート8の両先端に固定して取り付けられている捕獲用シート支持用ワイヤ3の一端が引き出されることで、その捕獲用シート支持用ワイヤ3が所定位置で捕獲用シート8を支持し、捕獲用シート8の捕獲機能をより強力なものとする。捕獲用シート固定器具10は、橋梁に固定設置されている格納容器9と捕獲用シート8を固定する機能を持つ器具である。
捕獲用シート8は、ゴム引き素材などからなり、圧搾空気が注入されると図4に示すように周辺部及び中央横断線部がチューブ形状に膨らみ、全体として長方形の板形状となる。
【0017】
[第2実施形態]
次に、本発明の第2実施形態について図5及び図6を参照して説明する。図5は本発明の第2実施形態に係る落下物捕獲装置の概略構成を示すものであり、図5(a)は正面図、図5(b)は側面図である。本実施形態は、本発明に係る落下物捕獲装置を建造物に設置したものである。図6は捕獲用シート8が動作したときの状態を示し、図6(a)は正面図であり、図6(b)は側面図である。図5及び図6において、図1から図4に示す第1実施形態の各構成部材と同等の部材には同一符号を付している。
【0018】
本実施形態の落下物捕獲装置は、上記第1実施形態の落下物捕獲装置と原理的に変わるところはない。ただし、圧力センサ2−1及び遮断検知センサ2−2の設置位置と、捕獲用シート支持用ワイヤ3、高速開閉器4、配管5、圧搾空気タンク6、制御システム7、捕獲用シート8、格納容器9及び捕獲用シート固定器具10の設置位置とは、本実施形態と第1実施形態では異なる。
【0019】
以上、本発明の実施形態を図面を参照して詳述してきたが、具体的な構成はこの実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等も含まれる。
例えば、捕獲用シート8は、圧搾空気が注入されると図4に示すように周辺部及び中央横断線部がチューブ形状に膨らみ、その周辺部と中央横断線部に囲まれた部位に網状部材を取り付けた構成としてもよい。
また、本発明に係る落下物捕獲装置は、設置対象が橋梁又は建造物に限定されるものではなく、崖っぷちなど自然物における人が転落しやすい場所、落石が起きやすい場所などを設置対象とすることもできる。
【0020】
【発明の効果】
以上の説明で明らかなように、本発明によれば、センサの検出信号に応じて捕獲用シートがシート形状となるので、通常時は捕獲用シートを小さく折り畳んでおくことができ、例えば落下危険ゾーンに人又は物体が侵入したときにだけ捕獲用シートが広がり、人命保護及び物体の破壊防止をすることができる。そこで、本発明によれば、例えば風等による構造物への影響を低減でき、火災時における避難又は救助活動の妨げにもならず、景観を損なうことがなく、違和感を持つなどの不都合を解消することができる落下物捕獲装置を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a falling object capturing device that captures a falling object from a bridge, a building, or the like.
[0002]
[Prior art]
Conventionally, in places such as bridges and buildings where a large number of people always gather, fall prevention nets, protection fences or tunnel nets are installed to prevent falls, and structures have been adopted to prevent people or objects from falling. (For example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-10-15095
[Problems to be solved by the invention]
However, conventional fall prevention nets, protective fences, tunnel nets and the like significantly impair the scenery and have disadvantages such as giving a sense of incongruity to other structures or scenery. In addition, conventional fall prevention nets, protective fences or tunnel nets have a structure that adversely affects the structure due to the wind and hinders evacuation and rescue, such as hindering the rescue activities of rescuers in case of fire. The fear of being a thing was undeniable.
[0005]
In addition, in places where people gather temporarily or where there are few people, a signboard or the like that warns about falling or falling is installed, and other protective measures may not be taken. However, in such a place, it is not known that an accident has occurred. For example, when a person falls, it is conceivable that even if a person does not die immediately after the fall, he or she is left alone and loses his or her life.
[0006]
The present invention has been made in view of the above-mentioned circumstances, and can suppress the influence on structures due to wind, etc., can avoid evacuation and rescue in the event of a fire, and impair the scenery or discomfort. It is an object of the present invention to provide a fallen object capturing device that can suppress inconveniences such as having a falling object and can exert a capturing function only when a person or an object enters a fall danger zone.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a fallen object capturing device according to claim 1 is a sensor that detects that an object has entered a predetermined area, and compressed air sending means that sends out compressed air according to a detection signal of the sensor. And a capture sheet formed into a sheet shape by the compressed air sent from the compressed air sending means.
[0008]
Here, the predetermined area is, for example, a fall danger zone. The sensor is preferably composed of a plurality of types and a plurality of detection means, and is preferably capable of detecting that a person or a relatively large object has entered the fall danger zone. Further, it is preferable that the compressed air sending means has a switch such as a solenoid valve which operates at a high speed while being operated by the detection signal of the sensor, and sends compressed air through the switch.
[0009]
Further, the capture sheet is preferably folded and stored at a lower portion or a side portion of a bridge, a building, or the like.For example, the compression is performed by inserting air into a folded rubber boat so as to be in a boat shape. Preferably, the sheet is formed by air. Therefore, when an object such as a person enters the fall danger zone, the capture sheet that has been stored is expanded into a sheet shape by compressed air, and the capture sheet for the person or the like that has fallen from the fall danger zone is formed. Can be captured.
Thus, according to the present invention, it is possible to protect the life of a falling person and prevent destruction due to falling of an object, and prevent occurrence of an accident and destruction of an object due to being caught by a falling object at a falling point. it can.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 shows a schematic configuration of a fallen object capturing device according to a first embodiment of the present invention. FIG. 1 (a) is a front view, and FIG. 1 (b) is a side view. FIG. 1 shows an embodiment in which a fallen object capturing device is installed on a bridge. This fallen object capture device includes a support 1, a pressure sensor 2-1, a cutoff detection sensor 2-2, a capture sheet supporting wire 3, a high-speed switch 4, a pipe 5, a compressed air tank 6, a control system 7, and a capture system. It is composed of a sheet 8, a storage container 9, and a capturing sheet fixing device 10.
[0011]
The column 1 serves as a starting point of the capturing sheet supporting wire 3 and is fixed to the bridge. The pressure sensor 2-1 is a sensor attached to a balustrade or the like and detects weight. The cutoff detection sensor 2-2 is attached to the support 1, and detects that a person or an object has entered a predetermined area by detecting that the object has blocked infrared light or laser light or the like.
[0012]
The capture sheet support wire 3 is a wire that supports the capture sheet 8. The high-speed switch 4 is composed of an electromagnetic valve or the like serving as an opening / closing means for switching whether to send compressed air from the pipe 5 to the capture sheet 8 at high speed. The pipe 5 serves as a passage for the compressed air sent from the compressed air tank 6 to the capture sheet 8. The compressed air tank 6 is filled with compressed air. The control system 7 controls the operation of the high-speed switch 4 based on the detection signals of the pressure sensor 2-1 and the cutoff detection sensor 2-2. The capture sheet 8 is expanded by compressed air sent out via the pipes 5 and the like to form a sheet. The storage container 9 is a container in which the capturing sheet is folded and stored in a bellows shape. The capture sheet fixing device 10 fixes or supports one side of the capture sheet 8 expanded into a sheet shape by compressed air. The symbol A in FIG. 1 indicates the direction in which the capture sheet extends.
[0013]
When a person or an object enters the danger zone, detection signals are output from a plurality of types and a plurality of sensors including the pressure sensor 2-1 and the cutoff detection sensor 2-2. Here, the fall danger zone refers to a position where the fall (fall) absolutely occurs. For example, a pressure sensor 2-1 installed on the railing of the bridge and sensing the weight, and the outside of the railing of the column 1 fixed to the bridge, which is the starting point of the wire 3 for sheet support integrally formed with the bridge By operating both of the cut-off detection sensor 2-2 disposed at the position where the absolutely falling (falling) is detected, the intrusion is detected and a detection signal is output.
[0014]
The detection signals output from the pressure sensor 2-1 and the cutoff sensor 2-2 are sent to the control system 7. The control system 7 receives the detection signal and recognizes that both the pressure sensor 2-1 and the cutoff sensor 2-2 have simultaneously operated, thereby determining that a person or an object has entered the danger zone. Then, upon determining that a person or an object has entered the dangerous falling zone, the control system 7 instantaneously sends an open signal to the high-speed switch 4 to bring the high-speed switch 4 into the “open” state. As a result, the compressed air filled in the compressed air tank 6 is instantaneously sent to the capture sheet 8 through the pipe 5 and the high-speed switch 4. Then, the capture sheet 8 folded and stored in the capture sheet storage container 9 in a bellows shape is expanded so as to spread in a sheet shape. The expanded capturing sheet 8 has a capturing function of capturing falling objects.
[0015]
FIG. 2 shows a state in which the capturing sheet 8 operates, FIG. 2 (a) is a front view, and FIG. 2 (b) is a side view. FIG. 3 shows a state in which the capture sheet 8 is stored in a bellows shape in the storage container 9, FIG. 3 (a) is a front view as viewed from the expansion direction, and FIG. 3 (b) is a top view. FIG. 3C is a side view. FIG. 4 shows a state in which the capturing sheet 8 has enabled the capturing function. FIG. 4 (a) is a top view and FIG. 4 (b) is a side view.
[0016]
As shown in FIGS. 1 to 4, the capture sheet 8 is formed into a sheet shape by injecting air in the same manner as when a rubber boat is folded into a target boat shape. When the compressed air is injected into the capturing sheet 8, the capturing sheet 8 is made of a rubberized material or the like having a strength comparable to that of wood. However, the falling object cannot be supported by the capturing sheet 8 alone. Then, the capture sheet 8 is expanded by injecting air, so that one end of the capture sheet supporting wire 3 fixedly attached to both ends of the capture sheet 8 is pulled out, and the capture sheet 8 is captured. The sheet supporting wire 3 supports the capturing sheet 8 at a predetermined position, thereby enhancing the capturing function of the capturing sheet 8. The capture sheet fixing device 10 is a device having a function of fixing the storage container 9 fixed to the bridge and the capture sheet 8.
The capture sheet 8 is made of a rubberized material or the like, and when compressed air is injected, the peripheral portion and the central transverse line portion swell into a tube shape as shown in FIG. 4 to have a rectangular plate shape as a whole.
[0017]
[Second embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 shows a schematic configuration of a fallen object capturing device according to a second embodiment of the present invention. FIG. 5 (a) is a front view, and FIG. 5 (b) is a side view. In this embodiment, a fallen object capturing device according to the present invention is installed in a building. 6A and 6B show a state when the capture sheet 8 operates, FIG. 6A is a front view, and FIG. 6B is a side view. In FIGS. 5 and 6, the same reference numerals are given to the same members as the respective constituent members of the first embodiment shown in FIGS.
[0018]
The fallen object capture device of the present embodiment is basically the same as the fallen object capture device of the first embodiment. However, the installation positions of the pressure sensor 2-1 and the cutoff detection sensor 2-2, the capturing sheet supporting wire 3, the high-speed switch 4, the pipe 5, the compressed air tank 6, the control system 7, the capturing sheet 8, and the storage The installation positions of the container 9 and the capture sheet fixing device 10 are different between the present embodiment and the first embodiment.
[0019]
As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the embodiments, and includes a design change or the like without departing from the gist of the present invention.
For example, when compressed air is injected into the capturing sheet 8, the peripheral portion and the central transverse line portion swell into a tube shape as shown in FIG. May be attached.
In addition, the fallen object capturing device according to the present invention is not limited to a bridge or a building, but may be a place where a person easily falls on a natural object such as a cliff, a place where a rock falls easily, or the like. You can also.
[0020]
【The invention's effect】
As is clear from the above description, according to the present invention, the capture sheet has a sheet shape in accordance with the detection signal of the sensor, so that the capture sheet can be normally folded small, and for example, the fall The capture sheet spreads only when a person or an object enters the zone, thereby protecting human life and preventing the destruction of the object. Therefore, according to the present invention, for example, it is possible to reduce the influence on the structure due to wind and the like, and it does not hinder evacuation or rescue activities in the event of a fire, does not impair the landscape, and eliminates inconvenience such as discomfort. A fallen object capturing device can be provided.
